What is docsIf3CmtsCmUsStatusRangingStatus?
This object reports the current ranging state of a cable modem during its upstream channel synchronization with the CMTS head-end. Ranging is the initial handshake where the modem adjusts power levels and timing offsets to align with the CMTS. Cable technicians monitor this value to diagnose modem provisioning failures and signal quality issues.
